T URBINE.

To all w'liom it menigeen/cern.-

Be it known that? If" RICHARD H. GoLns;

BOROUGH,` a' citizen ot the United Statesfre- "sidinggat'l/Vashington, inthe District of Columbia,` have invented certain new and use.- uljlmprovcments in Turbines, of which the folloWing, iS a Specification.

"My inventionrelates to turbines; and it consists in the constructions, combinations, and arrangements herein described land claimed. i

An object of inyinvention is to provide a whereby the several varies olf-the series can.

be expedientlyadjust ed in. their proper rela- A further -object of my invention. is to pro- 'vide improved means for assembling and securing annular series of vanes in turbines by of sendinga skilled turbine man from the' shops. y

Referring to the accompanying drawings, forming a part of' this application7 and in which similar reference-numerals indicate corresponding parts lin the several views, Figure -11 is a detail longitudinal sectional view through lthe upper half of-a turbine-rotor provided with oneembodiment of my invention. ".FigpZ is an elevation, on a smallerv scale,` showingaface of one of the rot orf-disks with aport-ion or ail-.annular series of vanos and their securingfring.in position. Fig/3 is a detail perspective view clearly illustrating the manner 'of connectin the annularseries of varies to one of theiannul'ar members of the turbine-rotor: Fig: l a view similar to illustrating aniotiiied constructitui; andFig.' .5 is a detail perspective view` show- Yi'ng ,the manner of connect irg the vaines to one of thefannular members of the rotor in the coiistruction illustratedin Fig. #L

The tivo rin Ois ci each pair are provided with series oi' registering recesses 8 for receiving the ends of the several vanes 9, in,

The apertures 6 are shown eri--v terposed between the front faces thereotfl application filed by me simultaneously with this application, and they obviate the tedious and expensive .machiningl and assembling necessary in previous constructions.

As shown especially in Fig. 3, gaskets 15,

of copperor other suitable material, are pref- 1 eralbly positioned in the several recesses 8 for avoiding unequal clamping-pressure on Vthe several vanos of the series through imperfect machining of the parts. Further, the gas-v kers .15 extend over only the Wider port-ions of the bottoms of the recesses, leaving the. narronv ends of said recesses free, thereby limiting the clamping-pressure to the thicker portions of the vanes and eliminating any` tendency to crush or distort the vthin edges thereof.

A spacing and shown positioned between thedisks 2, Witl i gaskets l1 interposed betweenthe' abutting surfaces` thereof. lA,seriesofboltsl2, err-1 tending through the disks 2,provit'les'means'- deflecting member 10 isf 1 for 'forcibly drawing said disks together,

thereby providing a common mea-ns1 fon clamping said diskstogether With the rotor members 3,1ings 5,' andvanes 9. vThis constitutes a very convenient and -eilicient means for securt-rlyT clamping the several parts and tends to produce a uniform pressure between the rings and vanes of the sev-` eral annular series.
